L. C. VINSLOW, OF CANTON, NEW YORK.

IMPROVEMENT IN CHEESE-PRESSES.

Secification forming part of Letters Patent N0. 41,113, dated January 5, 1864.

T0 all whom it may concern:

Be it known that I, L. C. IVINSLOW, of Canton, in the county of St. Lawrence and State of New York, have invented a new and Improved Cheese-Press; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a side sectional view of my invention, taken in the line x x, Fig. 2; Fig. 2, a front View of the same.

Similar letters of reference indicate corresponding parts in the two iigures.

This invention consists in the employment or use of a lever -frame provided with pawls and arranged with ratchet cam-wheels, pressure bars, and an adjustable cheesebed, as hereinafter described, whereby a very simple and efficient cheese-press is obtained.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

The framing of the device is composed of two uprights, a a, connected by a cross-piece, b, at their upper ends and attached to proper sill-pieces, c c.

A represents a shaft, which is fitted horizontally in the framing at about the center of its height, and has two wheels, B B, keyed iirmly upon it, one near each end. These wheels are each provided at their peripheries with ratchet-teeth d d', which extend nearly around the wheels, the teeth d having a reverse position to the teeth d. In each wheel B there are two scroll-shaped slots, e e', which extend from nearly the centers of the wheels toward their peripheries, those of each wheel being in opposite positions, as shown clearly in Fig. l.

C represents a lever-frame, which is composed of two parallel bars, f f, the inner ends of which are fitted loosely on the shaft A and allowed to work or turn freely thereon. The bars f, near their outer ends, are connected by cross-bars g, two of the latter being at each side'of the former, and in each bar f there is fitted a double pawl, D, said pawls being fitted on pins h, and having each two projections, i t", one to catch into the teeth d and the other to catch into the teeth d. (See Fig. 1, in

which the projections are shown by dotted lines.)

E represents a pressure-bar, which is tted horizontally inthe `upper part of the framing, its ends being provided with tenons which fit into mortises in the upper parts of the uprights a a, to admit of a vertical play of said bar. A similar bar, E, is fitted in the lower part of the framing. The upperpressure-bar, E, has two forked pendent arms, F F, connected to it by joints j, and said pendents have each a friction-roller, k, in their lower ends, said rollers being litt-ed in the slots e of the wheels B. The lower pressurebar, E, has two upright arms, F F', attached to it by joints j, and these arms have friction-rollers lo in their upper ends, which are fitted in the slots e of the wheels B. To the center of the lower pressure-bar, E', there is attached an upright, G, which passes-through amortise, Z, in a cheese-board, H. This cheese-board is of-rectangular form, and of such dimensions that it may be fitted between the wheels B B and rest upon the shaft A. The cheese-board has two hook-shaped cleats, m m, attached to its under side. The front part of the cheeseboard is connected by a joint, n, to the upper end of an upright, I, the lower end of which is connected by a joint, o, to a cross-bar, p, on the sill-pieces c c. rIhe cheese-board H may, when the upright G is withdrawn from it, be drawn forwarda certain distance to admit of the cheese-hoop being adj usted upon it, with the cheese or curd therein, the hook-cleats m limiting this movement, as indicated in red in Fig. l. On the upper end of the upright G afollower, q, is placed, which enters the lower end of the cheese-hoop, and a similar follower, r, is attached to the upper pressure-bar, E, by a screw, s.

v From the above description it will be seen that when thelever-frame C descends the projections i of the pawls D will engage with the teeth d of the wheels B and turn said wheels, so that the upper pressure bar, E, will be forced down and the lower pressure bar, E, forced upward, in consequence of the scrollshaped slots e e acting on the arms F F. This frame is pressed down by an extension-lever, J, which is fitted in the outer end of the frame C, and has a weight attached to it, so as to give a continuous pressure. Vhen the press- The ratchet cam-wheels B B and lever-franje ing operation is finished, the frame Gis .moved C, provided with the double pawls D, in comupward, the projections z' of the pawis D enbination with the cheese -board H, and the gaging with the teeth d of the wheels B, which pressure-bars E E, connected with the wheels are turnedin a reverse direction, so as to force B, as shown, al1 arranged to operate with or the pressure-bar E upward and the pressurewithout the extensioirlever J, substantially as bar E downward and admit of the cheese beand for the purpose herein set forth.

I claim as new, and desire to secure by Letters JAMES DUNN,
